Hugging Face has shipped major updates to its Kernels project, which standardizes how custom GPU kernels are packaged, distributed, and consumed. Key changes include a new 'kernel' repository type on the Hub for better discoverability, trusted publisher controls and code signing via Sigstore's cosign for improved security, a cleaner CLI separation between `kernels` and `kernel-builder`, expanded framework support (Torch Stable ABI and Apache TVM FFI), and foundational tooling for agentic kernel development workflows. Additional improvements cover one-click environment setup, system cards for kernels, a `has_kernel()` compatibility check API, and a fix for manylinux_2_28 libstdc++ linking issues that caused segfaults.
